The Gemini man enjoys diversity and he expects his partner to fulfill multiple roles: wife, mistress, mother and friend. The weakness in establishing a long term relationship with him is his constant desire for change and variety and his reluctance to settle down to a domesticated life style. As a Leo you should be able to provide lots of excitement and social activities to keep him happy. Both of you are generous and big spenders so you'll have to be in the high income bracket or there could be financial problems. If the Gemini man of your choice is not successful, perhaps you'd better think twice. The Gemini man paired with a Leo woman will have to learn how to share and how to curb any feelings of jealousy he may experience when others are drawn to your grace and glamor. With a little give and take on both sides the relationship could blossom into something really special.
